Hydrogen Water Basics
What is hydrogen water? 

Hydrogen water is regular water infused with extra molecular hydrogen gas (H₂). It’s produced through electrolysis or by dissolving magnesium-based stick packs, allowing water to retain dissolved hydrogen that may offer antioxidant properties.

What are the benefits of hydrogen water? 

Emerging research suggests molecular hydrogen may reduce oxidative stress, support metabolism, enhance athletic recovery, improve cognitive and skin health, and reduce inflammation. However, results are preliminary and not definitive.

When should I start seeing the benefits of hydrogen water?

Some users notice benefits within days or weeks, especially for recovery or hydration. Clinical studies often report noticeable effects after 4–8 weeks of regular use.

What research has been done on hydrogen water?

There are over 1,000 studies and more than 200 human clinical trials examining hydrogen water in relation to metabolism, recovery, inflammation, and cognition.

Doesn't water already contain hydrogen? 

Yes, H₂ is part of H₂O. Hydrogen water refers to extra dissolved molecular hydrogen gas (H₂) that is not chemically bound in water molecules.

How often should I drink hydrogen water?

Start with one bottle per day and increase gradually. Many people drink it daily for general support.

Can I drink too much hydrogen water? 

Hydrogen water is generally recognized as safe (GRAS). Very high intake may cause mild digestive effects like bloating or loose stools.

Does hydrogen water taste different?

Most people report no noticeable difference in taste. Some describe it as smoother or cleaner.

Is hydrogen water the same as alkaline or ionized water?

No. Hydrogen water contains dissolved H₂ gas and is pH-neutral. Alkaline water is defined by high pH levels and lacks consistent research support.

What’s the best way to get hydrogen? 

Use devices or stick packs that generate at least 0.5 PPM of dissolved hydrogen, the threshold shown to be potentially effective in research.

Is hydrogen water safe? 

Yes. It is FDA GRAS-designated and made with food-grade materials. As with any supplement, consult a healthcare provider if you are pregnant or have medical conditions.

What is a PPM?

PPM stands for 'parts per million,' a unit measuring the concentration of hydrogen gas in water. Therapeutic levels typically range from 0.5 to 4.5 PPM.

ECHO Flask Hydrogen Water Bottle
How many PPMs of hydrogen does it produce? 

The Echo Flask generates up to 6 PPM of dissolved hydrogen from a 10‑minute cycle and up to 8 PPM in a 20‑minute cycle.

Is the ECHO Flask H2 certified?

Yes. The Flask is certified to produce 8 PPM hydrogen based on third-party testing.

Do you have to refill the hydrogen?

Our flask generates molecular hydrogen (H2) fresh each time you run a cycle. The electrolysis process generates H2 directly from the water you put in. There are no cartridges to replace and no added chemicals or minerals are needed.

Does it need special water? 

Only use deionized (DI) or reverse osmosis (RO) water with the flask.

Does the ECHO Flask change water pH or add metals? 

No. The Flask maintains a neutral pH and does not introduce metals into the water.

Can I add supplements to the Flask? 

No. Supplements or additives should not be added to the Flask. Add them after hydrogenation in a separate container.

Can I put the Flask in the dishwasher?

No. The Echo Flask must be handwashed only. Avoid dishwashers and submerging the device.
